Complementary and alternative drug therapy versus science-oriented medicine

How does the role of complementary and alternative medicine in general practice differ between countries? Interviews with doctors who have worked both in Germany and elsewhere in Europe

BACKGROUND

Available data suggest that general practitioners (GPs) in Germany use complementary and alternative medicine (CAM) modalities more frequently than GPs in many other countries. We investigated the country differences perceived by general practitioners who have worked in Germany and in one of four other European countries with regard to the role of complementary and alternative treatments in primary care.

METHODS

In this qualitative study we conducted semi-structured interviews with 12 GPs who had worked both in Germany and Italy, the Netherlands, Norway or the United Kingdom (UK; n = 3 for each of the four countries). Participants were asked how they perceived and experienced country differences regarding health system, relevance of CAM modalities, the role of evidence-based medicine (EBM) and science, and how they handle so-called indeterminate situations. For the analysis, we followed a thematic analysis approach according to Braun and Clarke with focus on themes that cover CAM.

RESULTS

Participants unanimously reported that they perceived CAM to be more relevant in general practice in Germany compared to the other countries. We identified four overarching themes in relation to the perceived reasons for these differences. Firstly, physicians with experiences in countries with a strong EBM and science orientation (Netherlands, Norway and the UK) considered the deeply ingrained view in national healthcare systems and GP communities that CAM modalities are not evidence-based as the main reason for the lower use of CAM by GPs. Secondly, extensive training of communication skills was cited as a reason that reduced the need for CAM in the Netherlands, Norway and the UK. Thirdly, differences in patient expectations and demands were perceived as a factor contributing to greater utilisation of CAM by German GPs compared to the other countries. Finally, country-specific reimbursement mechanisms were considered as a factor influencing the role of CAM in general practice.

CONCLUSIONS

The study results point to major differences between countries with regard to the role of CAM in GP care. Differences in basic attitudes in the discipline of general practice, patient expectations and system conditions appear to play an important role here.

Use of complementary and alternative therapies by patients with eye diseases: a hospital-based cross-sectional study from Palestine

BACKGROUND

Generally, complementary and alternative therapies (CAT) are accepted methods of treatment by patients with various types of conditions. Their use is becoming especially prevalent among patients with eye problems even in developed countries. Thus, we aimed to determine the pattern of use of CAT in this patient population, to identify the patient characteristics associated with the use of CAT, and to assess the types of CAT used.

METHODS

A descriptive, cross-sectional study was conducted in Palestine at An-Najah National University Hospital between the time periods of October 2019 to May 2020, using questionnaire-based face to face interviews. Data were collected through convenience sampling. Patients responded to the questionnaire, which was focused on information adapted from previous research in this area, covering socio-demographic and clinical characteristics, types of CAT, source of information, and side effects on CAT use.

RESULTS

A total of 86 patients were interviewed for our study. Over two thirds, 67% reported using CAT for the specific purpose of improving their eye condition, and about one third (29.1%) received more than one therapy. The most common therapies reported were duea' (i.e. supplication) (47.1%) and herbal therapies (24.1%). It was shown that patients with bilateral involvement of their eyes were almost twice more likely to describe using CAT than patients with unilateral eye pathology (p = 0.006). Also, patients who underwent surgery as their route of treatment were significantly less likely to use CAT (p = 0.043). Most of our study participants mentioned a non-physician source as their source of information regarding CAT with family members being the most frequently mentioned (30.2%) followed by the internet (25.6%) and friends (19.8%).

CONCLUSIONS

The prevalence of CAT use among patients with eye disease is somewhat high in our study population. Because CAT may trigger adverse reactions, influence the progression of the disease, and interfere with conventional treatment, the ophthalmologist should frequently be asked patients with such diagnostics regarding the use of these therapies. Further work is required to analyze the mechanisms of action and to establish realistic guidelines for the use of these modalities.

Types of Medication-Assisted Treatment for Opioid Use Disorder in Turkey: The Perceptions of Inpatients about Treatment Success

OBJECTIVE

The aim of this study was the following. When the different dynamics of agonist or antagonist treatments considered it is assumed that the eligible treatment to the individual may be maintained with high efficacy. Thus, we aimed to examine the difference between treatment methods, considering sociodemographics and positive perception for treatment success.

METHODS

The number of 136 individuals which their ages range between 19-50 and have been getting agonist (buprenorphine/naloxone) or antagonist (naltrexone) treatment because of opioid use disorder while resting in clinics have been evaluated to reveal the factors that may alter their perception about treatment and have been compared with sociodemographic variables and characteristics such as sociotropic and autonomic. Therefore, "Sociodemographic Data Evaluation Form," "Predictive Factors for The Addiction Treatment Success Scale," and "Sociotropy-Autonomy Scale" were used to assess the sociodemographic data, the perception towards factors which have been affected to the treatment and characteristics. The data of the individuals have been collected by the researcher via face-to-face interviews while patients were residential in the clinic.

RESULTS

According to results of our study, it has been detected that there are some differences in the perception of treatment success between individuals who have been getting agonist or antagonist treatments such as treatment method (p<0.05), treatment frequency (p<0.01) and parents' vital statuses (p<0.05).

CONCLUSION

At the end of the study it has been understood that medical and social benefits after the selection of eligible treatment methods which is suitable for individual's perception and characteristics have to be considered.

How German general practitioners justify their provision of complementary and alternative medicine - a qualitative study

BACKGROUND

Many German general practitioners (GPs) use complementary and alternative medicine (CAM) in their daily work although most CAM procedures are controversial from an academic point of view.

OBJECTIVE

We aimed to investigate how GPs justify their use of CAM.

METHODS

We performed semi-structured, individual face-to-face interviews with 20 purposively sampled, experienced GPs providing primary care within the framework of the German statutory health insurance system. A grounded theory approach was used for data analysis.

RESULTS

All GPs participating in this study used at least some CAM in their clinical practice. Participants did not have any major conflicts when justifying their use of CAM therapies. Important arguments justifying CAM provision were: using it as a supplementary tool to conventional medicine; the feeling that evidence and science leave many problems in primary care unanswered; a strong focus on helping the individual patient, justifying the use of procedures not based on science for therapeutic and communicative purposes; a strong belief in one's own clinical experience; and appreciation of placebo effects. In general, participants preferred CAM therapies which seemed at least somewhat plausible to them and which they could provide in an authentic manner.

CONCLUSIONS

Our results suggest that many German GPs integrate CAM treatments in their routine primary care work without perceiving any major internal conflicts with professional ideals.

Use and acceptance of complementary and alternative medicine among medical students: a cross sectional study from Palestine

BACKGROUND

Teaching Complementary and alternative medicine (CAM) in medical schools is becoming prevalent worldwide. Few studies have been conducted to evaluate medical students' knowledge and attitude toward CAM. Therefore, this study was designed to assess CAM knowledge, attitudes, and beliefs among Palestinian medical students.

METHODS

This study was developed in a cross-sectional design. It targeted medical students at An-Najah National University, between January and April of 2018. We gathered the data from students using a questionnaire printed as a hard copy. Medical students of both sexes in their 4th, 5th, or 6th year of studies were included in the survey. The questionnaire consisted of 3 sections: demographic characteristics and detailed practices of the participants, their attitude and held beliefs towards CAM, and their knowledge on CAM. Mann-Whitney U Test and Kruskal-Wallis Test were used to test if there were differences between knowledge about CAM and the characteristics of the participants.

RESULTS

Of the 300 medical students who were offered the questionnaire, 251 students (43.8% male and 56.2% female) were included in the final analysis. Out of a maximum of 8 points, the mean knowledge score of the participants was 2.0 ± 1.6. The Kruskal-Wallis test showed a statistically significant difference in overall knowledge score among students of different year groups, with students at lower levels obtaining higher scores (P < 0.001). Additionally, the highest knowledge scores were found in students with low income, and students who came from the Palestinian refugee camps (P < 0.001). Students frequently recommended CAM modalities, with herbal medicine being the most recognized and used CAM modality and Ayurvedic medicine being the least recognized and recommended one. Social media was the most popular source of information about CAM, cited by 72.9% of the participants. Participants generally had a good attitude towards CAM but held varying beliefs about it.

CONCLUSIONS

In the current study, a knowledge gap regarding CAM was found among medical students in our sample, despite their good attitude towards the subject. Also, there was a general acceptance to include materials on CAM within the curriculum of medical students.

The Contribution of Complementary and Alternative Medicine to Reduce Antibiotic Use: A Narrative Review of Health Concepts, Prevention, and Treatment Strategies

AIM

The aim of this narrative review was to explore the potential contributions of CAM to reduce antibiotic use.

METHODS

We searched PubMed, Embase, and Cochrane Database of Systematic Reviews with a specific, limited set of search terms and collected input from a group of expert CAM researchers to answer the question: What is known about the contribution of CAM health and health promotion concepts, infection prevention, and infection treatment strategies to reduce antibiotic use? Results. The worldview-related CAM health concepts enable health promotion oriented infection prevention and treatment aimed at strengthening or supporting the self-regulating ability of the human organism to cope with diseases. There is some evidence that the CAM concepts of health (promotion) are in agreement with current conceptualization of health and that doctors who practice both CAM and conventional medicine prescribe less antibiotics, although selection bias of the presented studies cannot be ruled out. There is some evidence that prevention and some treatment strategies are effective and safe. Many CAM treatment strategies are promising but overall lack high quality evidence.

CONCLUSIONS

CAM prevention and treatment strategies may contribute to reducing antibiotic use, but more rigorous research is necessary to provide high quality evidence of (cost-)effectiveness.

Complementary and alternative medicine contacts by persons with mental disorders in 25 countries: results from the World Mental Health Surveys

AIMS

A substantial proportion of persons with mental disorders seek treatment from complementary and alternative medicine (CAM) professionals. However, data on how CAM contacts vary across countries, mental disorders and their severity, and health care settings is largely lacking. The aim was therefore to investigate the prevalence of contacts with CAM providers in a large cross-national sample of persons with 12-month mental disorders.

METHODS

In the World Mental Health Surveys, the Composite International Diagnostic Interview was administered to determine the presence of past 12 month mental disorders in 138 801 participants aged 18-100 derived from representative general population samples. Participants were recruited between 2001 and 2012. Rates of self-reported CAM contacts for each of the 28 surveys across 25 countries and 12 mental disorder groups were calculated for all persons with past 12-month mental disorders. Mental disorders were grouped into mood disorders, anxiety disorders or behavioural disorders, and further divided by severity levels. Satisfaction with conventional care was also compared with CAM contact satisfaction.

RESULTS

An estimated 3.6% (standard error 0.2%) of persons with a past 12-month mental disorder reported a CAM contact, which was two times higher in high-income countries (4.6%; standard error 0.3%) than in low- and middle-income countries (2.3%; standard error 0.2%). CAM contacts were largely comparable for different disorder types, but particularly high in persons receiving conventional care (8.6-17.8%). CAM contacts increased with increasing mental disorder severity. Among persons receiving specialist mental health care, CAM contacts were reported by 14.0% for severe mood disorders, 16.2% for severe anxiety disorders and 22.5% for severe behavioural disorders. Satisfaction with care was comparable with respect to CAM contacts (78.3%) and conventional care (75.6%) in persons that received both.

CONCLUSIONS

CAM contacts are common in persons with severe mental disorders, in high-income countries, and in persons receiving conventional care. Our findings support the notion of CAM as largely complementary but are in contrast to suggestions that this concerns person with only mild, transient complaints. There was no indication that persons were less satisfied by CAM visits than by receiving conventional care. We encourage health care professionals in conventional settings to openly discuss the care patients are receiving, whether conventional or not, and their reasons for doing so.

A retrospective cost-analysis of additional homeopathic treatment in Germany: Long-term economic outcomes

OBJECTIVES

This study aimed to provide a long-term cost comparison of patients using additional homeopathic treatment (homeopathy group) with patients using usual care (control group) over an observation period of 33 months.

METHODS

Health claims data from a large statutory health insurance company were analysed from both the societal perspective (primary outcome) and from the statutory health insurance perspective (secondary outcome). To compare costs between patient groups, homeopathy and control patients were matched in a 1:1 ratio using propensity scores. Predictor variables for the propensity scores included health care costs and both medical and demographic variables. Health care costs were analysed using an analysis of covariance, adjusted for baseline costs, between groups both across diagnoses and for specific diagnoses over a period of 33 months. Specific diagnoses included depression, migraine, allergic rhinitis, asthma, atopic dermatitis, and headache.

RESULTS

Data from 21,939 patients in the homeopathy group (67.4% females) and 21,861 patients in the control group (67.2% females) were analysed. Health care costs over the 33 months were 12,414 EUR [95% CI 12,022-12,805] in the homeopathy group and 10,428 EUR [95% CI 10,036-10,820] in the control group (p<0.0001). The largest cost differences were attributed to productivity losses (homeopathy: EUR 6,289 [6,118-6,460]; control: EUR 5,498 [5,326-5,670], p<0.0001) and outpatient costs (homeopathy: EUR 1,794 [1,770-1,818]; control: EUR 1,438 [1,414-1,462], p<0.0001). Although the costs of the two groups converged over time, cost differences remained over the full 33 months. For all diagnoses, homeopathy patients generated higher costs than control patients.

CONCLUSION

The analysis showed that even when following-up over 33 months, there were still cost differences between groups, with higher costs in the homeopathy group.

Non-conventional practice versus evidence-based medicine. A scientific and ethical analysis of the Italian regulation

BACKGROUND

The current lack of scientific validation of non-conventional treatments in medicine, whose epistemological foundations lie in scientific evidence and experimentation, raises significant questions regarding the costs and benefits of alternative-treatment forms. Nonetheless, in the last few decades non-conventional treatments have been increasingly recognised by the Italian medical profession, with one regional healthcare administration adopting some non-conventional practices as part of its conventional healthcare services.

AIMS

The Authors aim to analyse non-conventional treatments in medicine from an epistemological, cultural, ethical, political and economic point of view, in order to highlight criticalities and incongruities, especially when these treatments are approved by a public healthcare system, which should be grounded on the "evidence-based medicine" principle.

CONCLUSIONS

Non-conventional treatments in medicine are constituted by meta-theories, i.e. philosophical, religious and ideological concepts that conflict with contemporary rational, empirical medicine. In the interest of patients and society, the paper stresses the incongruity of a healthcare system which, despite being grounded on the "evidence-based medicine" principle, allows the development of non conventional treatments. Having said that, medical science should address not only the biological domain of illness but also its existential implications. Awareness and respect for the individual experience can undoubtedly lead to a new medical model that allows for a more effective therapeutic intervention.

Whole Medical Systems versus the System of Conventional Biomedicine: A Critical, Narrative Review of Similarities, Differences, and Factors That Promote the Integration Process

BACKGROUND

There is an increasing need for a worldwide professional integration of conventional medicine and traditional/complementary whole medical systems (WMSs). However, the integration is perceived by conventional medicine as problematic or unacceptable, because of a supposed lack of evidence for specific effects of WMSs therapies and supposed prescientific or unscientific paradigms of WMSs.

OBJECTIVES

To review the literature on the features of WMSs, similarities and differences between conventional medicine and WMSs, and scientific and clinical practice issues that should be dealt with in order to promote the integration process.

METHODS

A critical, narrative review of the literature on six WMSs.

RESULTS AND CONCLUSIONS

Key factors for the integration of WMSs and conventional medicine are as follows: legal frameworks, quality standards, high-quality research on safety and efficacy of WMS interventions, infrastructure, and financial resources. For scientific assessment of WMSs, there are unresolved ontological, epistemological, and methodological issues and issues of diagnostics, therapy delivery, and outcome assessment in clinical practice. Future research not only should be directed at quality assurance and generating the necessary data on safety and efficacy/effectiveness but also should address more fundamental (ontological, epistemological, and methodological) issues, in order to overcome the differences between WMSs and conventional medicine.

Prevalence and Perspectives of Complementary and Alternative Medicine among University Students in Atlanta, Newcastle upon Tyne, and New Delhi

Objective. A cross-cultural comparative study was developed that surveyed university students in Atlanta (United States), New Delhi (India), and Newcastle upon Tyne (United Kingdom) to understand the prevalence and perspectives of CAM in three urban societies with different healthcare systems. Design. Surveys were sent to students in the three aforementioned cities. Survey distribution occurred over 6 months from May to November 2015. A total of 314 surveys were received. Results. Dietary and vitamin supplements had the highest prevalence collectively (n = 203), followed by meditation, yoga, and massage. Commentary analysis showed the importance of science and evidence in justifying CAM practice. Conclusions. Matching the most prevalent practices with their designated NCCAM categories suggested that the students were attracted to biologically based, body-based, and mind-body practices as the central themes of attraction. Selected and prevalent CAM practices suggested the students' desire to maintain physical and mental fitness. Access to healthcare may have influence on the prevalence of CAM. Indian students were more likely to view CAM as a viable alternative to conventional medicine.
